Luhua party
At night, the enemy stared at the big dark reed pond from the small window of the turret, and the stars in the sky seemed to be immersed in the water and were about to fall. Late at night, waterfowl fly and sing in the reed pond. During the day, they hide in their nests to avoid gunfire. The reed is still trying so hard to drill up, and the goal seems to be the sky.
……
The boatman is an old man in his late sixties. This ship is a sharp one. The old man, wearing only a pair of blue shabby shorts, stood at the stern with a penny in his hand.
The old man has little meat and is as thin as an old osprey. However, the tanned face and short white beard are particularly energetic, but those deep-set eyes are particularly bright. It is rare to see such sharp and bright eyes, except on Baiyangdian Lake.
Old people go in and out of the water store every night, and their work scope is very wide: internal and external transportation, grain and grass transportation, and cadre escort; And there is no gun. He said to the responsible comrades in Tang Wei: You depend on me for everything, and my water supply and all insurance depend on my ability.
The old man is overconfident and self-respecting. Every night, on the water tightly blocked by the enemy, like an innocent man, he propped up the boat according to the leisurely mood of going out early and returning late to fish and cast nets, and fabricated things that made him happy and made others happy.
Because of him, the enemy's wishes have not come true.
Every night, the songs in the reed pond are still so loud, unlike those sung by hungry people; The reed pond also smells of rice and fat fish. The enemy is very worried.
……
The old man sat down feebly and the boat stopped there. The moon went down, and there was some rustling wind in the reed pond after midnight. The old man sighed and paused for a long time before saying:
"I can't send you in."
"Why?"
The old man looked straight ahead and said:
"I am ashamed to meet people."
……

Who knew this place, but ... it went through the old man's heart like a renju arrow. He can't explain: how many rivers and seas have he walked, and why didn't he finish the task this time? I have no children. How lovely these two children are! Usually talk big, this time I went in with a flower-hanging person. How can I speak? This old face! He called Daling and said:
"They hurt you and shed so much blood. I'll call them ten to bleed tomorrow! "
The two children didn't answer, and the old man felt despised. He said:
"If you don't believe me, I won't tell you. Who made a fool of me? However, wait until dawn, you will understand! "
The little girl said:
"You are so old, can you still fight?"
The old man ruthlessly say:
"Why not? I don't have to shoot them, that's not my skill. Those who want to see it, come and see it tomorrow! Erling, come with me tomorrow. Busy! "

Physics Reference Answers for Grade Eight (I)
First, multiple-choice questions (*** 15 questions, 2 points for each question, 30 points)
The title is1234567891012131415.
Answer b, d B D C C C A A B C D D D D D D D D D, d
Fill in the blanks (***7 questions, each empty 1 point, 18 point)
16. Frequency timbre 17. Bb3.o 18.m/smm 19。 Dynamic 85.
20. The convexity is 400 2 1. Reflection and refraction of water and air 22. Melting and heat absorption of Ninghua liquefied popsicle
4. Inquiry and experiment questions (***5 questions, 7 points for 28 questions, 6 points for 3 1 question, and 28 points for the rest 1 point)
27. Elastic vibrating air can't be a vacuum and can't transmit sound.
28.( 1) Range division value (2) If there is too much water, pour out some water (or open it).
When the water temperature is too low at the initial stage of heating, change hot water for experiments; Or use the inside of the alcohol lamp.
The flame heating is changed to external flame heating, and other answers are reasonable)
(3) Before boiling (4)98 (5) as shown on the right.
29.( 1) Vertical (2) Compare the sizes of images and objects (3) Place white paper vertically.
At the chess piece B, remove the chess piece B and directly observe the white paper to see if this image can be used.
Is it on white paper (can you explain how to put white paper and get 1 point, and how to observe it?
White paper won 1 minute). The image can't be written on a blank sheet of paper (1 minute) and it is fictitious (1 minute) (4) Don't turn to yourself for help.
30.( 1) (2) Slide (or projection)
3 1.( 1) paper drop height; Time when the paper falls; (2) Electronic Scale Watch
(3)2 points (if one of the three physical quantities in the table is missing, deduct 1 point until completion).
Frequency, altitude/meter time/second speed/meter? s- 1
Five, short answer questions (***2 questions, 3 points for each question, 6 points)
32. Think that the schoolbag can be moving or static (1), and give 2 points for the correct reference.
33. Using flat mirror imaging (1) can see the back of teeth. After the flat mirror is baked on the flame, the temperature rises, which can prevent the water vapor in the mouth (1) from liquefying on the mirror (1).
VI. Calculation questions (***2 questions, 34 questions with 4 points, 35 questions with 6 points, 10 points)
34.( 1)t = 1 1h( 1)
(2)s = 506 km
V = s/t (1 point)
= 506 km/1 1 hour (1 minute)
= 46 km/h (1 min)
35.( 1)v 1 = 55km/h t 1 = 24min = 0.4h( 1)。
S = v1t1= 55km/s× o.4h = 22km (2 points).
(2) V2 = 400km/h
T2 = s/v2 = 22km/400km/h = 0.055h = 3.3min (2 points).
T = t 1–T2 = 24 minutes -3.3 minutes = 20.7 minutes (1).
(Note: the result of the calculation problem is wrong because the previous calculation error is substituted into the back, and the back is not deducted.)
Additional questions (* * * two questions, 36 questions with 4 points, 37 questions with 6 points, 10 points)
36.( 1) Put a candle at the leftmost end of optical bench, put a light screen at the rightmost end, and put a convex lens next to the light screen;
(2) gradually moving the convex lens away from the light screen until a clear and reduced candle flame image appears on the light screen;
(3) read out the distance s from the convex lens to the optical screen on the optical bench, and the focal length of the convex lens is approximately equal to S. ..
37.( 1) Cyclists start 5 seconds later than runners; Cyclists are faster than runners. (Other information is acceptable as long as it is reasonable.)
② Distance
(3) See the figure below.
(4) As long as the topic is in line with the meaning of the topic, the answer corresponds to the topic (supplementary information is not scored).
